OSHA 10 Maritime common mistakes
OSHA 10 Maritime · Understand the traps and how to avoid them.
Treating the OSHA 10 Maritime course as a general construction or general industry course and applying 29 CFR 1926 or 1910 fall-protection and hazard rules to longshoring and shipyard scenarios instead of the maritime Parts 1915, 1917, and 1918.
Most free study material and prior safety training candidates already hold is built around construction and general industry, so the default mental frame is the wrong subpart set; the maritime parts share concepts but differ in scope, definitions, and specific numbers.
What to do instead
Before answering, classify the scenario: shipyard/repair (1915), marine terminals/longshoring (1917), or commercial diving (1918). Memorize the three part numbers and one distinguishing rule for each, and when a question names a vessel, terminal, or shipyard, consciously switch out of the 1926/1910 frame.
Confusing the employer's general duty to provide a workplace free of recognized hazards under Section 5(a)(1) with the specific standard that actually governs the task, and citing the general duty clause as the answer whenever no obvious rule comes to mind.
The general duty clause is memorable and sounds universally correct, so it becomes a catch-all choice; candidates do not check whether a specific maritime standard already addresses the hazard, which is the actual legal preference.
What to do instead
Use a two-step test: first ask whether a specific standard in Parts 1915/1917/1918 covers the hazard (it almost always does for falls, ladders, gear, and cargo handling); only select the general duty clause when no specific standard applies. Practice by naming the specific subpart for each of the ten most common maritime hazards.
Confusing employee rights and the inspection process: mixing up the employee's right to request an inspection, the right to accompany the compliance officer, the right to be free from retaliation, and the timelines for contesting citations.
These are taught together as a list, so the distinct triggers and time limits blur; candidates remember that a right exists but attach it to the wrong actor or the wrong deadline.
What to do instead
Build a small table with columns for who holds the right, what action triggers it, and the time limit (for example, the period for contesting a citation versus the period for abatement). Recall it by actor rather than by reciting the list in order.
Mixing up recordkeeping thresholds and reporting duties, such as which injuries must be recorded on the OSHA 300 log versus which must be reported directly to OSHA, and within what time frame.
Recording and reporting are both 'paperwork' obligations, so the criteria (treatment beyond first aid, days away or restricted duty, hospitalization, amputation, eye loss) get merged, and the short reporting windows are easily forgotten.
What to do instead
Separate the two concepts: recording is about severity and work-relatedness over the calendar year; reporting is about a short list of severe events with tight deadlines. Memorize the severe-event list and its deadlines as a distinct set, and practice sorting sample scenarios into record, report, or neither.
Applying fall-protection thresholds and equipment rules from the wrong subpart, for example using the construction fall-distance or guardrail numbers on a shipyard scaffold or an unprotected deck edge instead of the applicable maritime requirement.
Fall protection is the highest-frequency topic on the exam, and the numbers differ across subparts; under time pressure the most recently studied number wins rather than the one tied to the scenario's part.
What to do instead
Anchor each fall scenario to its part first, then recall the number. Keep a one-page comparison of fall-protection trigger heights, guardrail dimensions, and lanyard/anchor requirements by part, and rehearse the shipyard deck-edge and scaffold cases specifically.
Treating ladders, stairways, and gangways as interchangeable and applying the wrong angle, clearance, or securing requirement, or assuming a portable ladder rule covers a fixed ship's ladder or a gangway between vessel and shore.
Access equipment looks similar across environments, so candidates default to the familiar portable-ladder rule; vessel access also involves unique conditions such as tidal change, trim, and list that generic rules do not address.
What to do instead
Learn access equipment by location: shore-side terminal, shipyard, and vessel. For each, note the required angle or slope, the securing method, and how movement from tide or cargo operations is compensated. Flag any question mentioning gangways or accommodation ladders as a vessel-access question.
Underestimating or misclassifying confined-space and atmospheric hazards, treating a cargo hold, tank, or void space as an ordinary work area and skipping the permit, testing, or attendant requirements.
Confined-space questions are written as ordinary-sounding tasks, and candidates focus on the task rather than the space classification; the sequence of test, permit, attendant, and rescue readiness is long and easy to truncate.
What to do instead
Memorize a fixed entry sequence and apply it to every space question: identify and classify the space, test the atmosphere before and during entry, issue the permit, post the attendant, and confirm rescue capability. Practice naming which step is missing from a described scenario rather than recalling the whole list.
Confusing cargo-handling and gear-inspection responsibilities in longshoring, such as who inspects slings, shackles, and spreaders, how often, and what the removal-from-service criteria are, and mixing these with the vessel crew's duties.
Longshoring involves split responsibility between the terminal employer, the vessel, and the gear owner, and the inspection intervals and rejection criteria are specific numbers that are easy to swap.
What to do instead
Map responsibility by role: employer, gear owner, and vessel. Then memorize the inspection frequency and the defect thresholds that require removal from service for slings, chains, and hooks. When a question asks 'who,' answer from the role map before considering the technical rule.
Guessing at electrical, welding, or hot-work requirements in shipyard and vessel contexts, including grounding and assurance of de-energization, without distinguishing shipyard rules from longshoring and general industry rules.
Hot work and electrical safety are familiar from other courses, so candidates reuse general industry answers; maritime settings add vessel-specific conditions such as working aloft, wet environments, and hot work near combustible cargo residues.
What to do instead
Study hot work as a permit-driven process: authorization, fire watch, area preparation, and post-work monitoring. For electrical work, memorize the de-energization and verification sequence rather than the equipment details. Note explicitly where the shipyard part differs from general industry.
Answering 'who must do what' questions from memory of the org chart instead of the standard, for example assuming the compliance officer, the employee, or the vessel master holds a duty that the regulation assigns to the employer.
The exam repeatedly tests allocation of duty, and candidates read the scenario as a story about people rather than as a question about the employer's legal obligation; the employer is the party almost always responsible under OSHA standards.
What to do instead
Adopt a default: unless the question is specifically about employee rights or the compliance officer's authority, the duty belongs to the employer. Read the stem for the words 'must provide,' 'must ensure,' and 'must train,' and answer with the responsible party before selecting the substantive requirement.
